“…The increase in micro-hardness may also be credited to increasing the time of irradiation. These results are in agreement to those of Jelani et al (2013), who revealed the increasing trend of micro-hardness analysis [33]. They observed the variation of micro-hardness of excimer laser irradiated Zr as a function of laser fluence.…”

Aluminium samples are irradiated using a continuous-wave diode laser in a laboratory environment to study the effect on its surface, structural, and mechanical properties. The exposed samples are investigated by scanning electron microscopy and x-ray diffractometer for the surface and structural morphology, respectively. The scanning electron microscopic analysis unveils the realization of micrometer grain size, exfoliational sputtering, and crater production. The diffractometric x-ray analysis reveals the grain size, d-spacing, and dislocation line density of the targeted samples. The hardness of the samples as a function of exposure time is investigated using the micro Vickers hardness tester to perceive the mechanical properties. An increase in micro-hardness is observed with the increase in the exposure time.

“…Laser ablation is being widely used for surface structuring, chemical processing, and growth of thin films of a variety of materials. Textured surfaces with micro-and nano-scale morphological features show significantly altered physical, electrical, and mechanical properties (Latif et al, 2012;Jelani et al, 2013). A laser initiates a variety of processes upon interaction with the material through various energy transfer mechanisms depending on the irradiation conditions (Crouch et al, 2004).…”

The effect of laser-irradiance on the surface morphology and laser induced breakdown spectroscopy of zinc has been investigated by employing Nd:YAG laser (wavelength λ = 1064 nm, pulse duration t ~ 10 ns, and repetition rate = 10 Hz) under ambient environment of argon at a pressure of 20 Torr. For this purpose, zinc targets were exposed to various laser irradiances ranging from 13 GW/cm2 to 100 GW/cm2. Scanning electron microscope analysis has been performed to analyze the surface modification of irradiated zinc targets. Scanning electron microscope analysis revealed the formation of various kinds of structures such as ripples, cones, cavities, and wave like ridges at the center and peripheral regions of ablated zinc. In the central ablated region with increasing laser irradiance, the growth of distinct and well defined ripples is observed. Further increase in irradiance makes the appearance of these ripples diffusive and narrow. In order to correlate the plasma parameters with the surface modification, laser induced breakdown spectroscopy analysis has also been performed. The electron temperature and number density of zinc plasma have been evaluated at various laser irradiances. For both plasma parameters, an increasing trend up to a certain value of laser irradiance is observed which is due to enhanced energy deposition. Afterword a decreasing trend is achieved which is attributed to the shielding effect. With further increase in irradiance a saturation stage comes and almost no change in plasma parameters is observed. This saturation is explainable on the basis of the formation of a self-regulating regime near the target surface. A strong correlation between surface modification and plasma parameters is established.

“…The occurrence of highly confined plasma pressure, efficient cooling, enhanced chemical reactivity, generation of elevated temperatures, pressures and shock waves make this technique highly useful and beneficial [8,9]. Micro/nanostructures formation [5,6], plasma analyses [10] and oxide/nitride/formation [11] during micro, nano and fs laser ablation of zirconium in gaseous environment is reported in literature [12,13]. Ursu et al [14] studied the nitriding and oxidizing of Ti and Zr samples by the action of microsecond pulsed transversely excited atmospheric CO 2 laser irradiation in the presence of a nitrogen and oxygen gas environment However, the ablation of zirconium in liquid confined environment is inadequately reported [15].…”
